Texas Instruments F28384DZWTQR

Overview

F28384DZWTQR from Texas Instruments is a dual-core real-time microcontroller integrating two 200-MHz C28x DSP CPUs, one 125-MHz Arm Cortex-M4 Connectivity Manager (CM), IEEE 754 double-precision FPU, 512KB flash per C28x core, and 512KB CM flash - designed for high-fidelity motor control, digital power conversion, and industrial Ethernet edge nodes.

For engineers reviewing the F28384DZWTQR datasheet, F28384DZWTQR pinout, F28384DZWTQR application, or F28384DZWTQR equivalent, key selection criteria include dual-CPU deterministic latency, EtherCAT Slave Controller integration, CAN FD + USB 2.0 + 10/100 Ethernet support, and functional safety certification up to ASIL B / SIL 2.

Technical Context

The F28384DZWTQR implements a heterogeneous dual-domain architecture: the C28x subsystem handles time-critical PWM generation (32 channels, 16 high-resolution), ADC sampling (4× 16-bit/1.1 MSPS), and CLA-accelerated control law execution, while the isolated Cortex-M4 CM manages protocol stacks (EtherCAT, USB, Ethernet 1588), security (AES), and host interface bridging without CPU1/CPU2 interruption.

Its system-level features include dual-zone security with UID, ERAD debug trace, background CRC (BGCRC), hardware BIST, and configurable logic blocks (8 CLB tiles) for custom peripheral augmentation - all operating under 1.2-V core / 3.3-V I/O with thermal design validated for 125°C junction operation in the ZWT nFBGA package.

FAQ

What is the core architecture of the F28384DZWTQR?

The F28384DZWTQR integrates two independent TMS320C28x 32-bit DSP CPUs running at 200 MHz, each with IEEE 754 double-precision FPU and Trigonometric Math Unit (TMU), plus a dedicated Arm Cortex-M4 Connectivity Manager (CM) operating at 125 MHz. This heterogeneous dual-core architecture allows simultaneous real-time control and protocol handling - critical for applications like servo drives and solar inverters where deterministic latency and communication throughput must coexist.

Does the F28384DZWTQR support EtherCAT communication?

Yes, the F28384DZWTQR includes a hardware EtherCAT Slave Controller (ESC) integrated into its Connectivity Manager subsystem. It supports full EtherCAT protocol stack execution with dual-port PHY interface, enabling sub-100-µs cycle times and synchronization accuracy compliant with IEC 61158. The ESC operates independently of the C28x CPUs, preserving real-time control bandwidth while managing network traffic - a key differentiator for industrial automation nodes using F28384DZWTQR.

What analog capabilities does the F28384DZWTQR provide?

The F28384DZWTQR features four high-precision analog-to-digital converters (ADCs), each capable of 16-bit resolution at 1.1 MSPS or 12-bit at 3.5 MSPS, with 12 differential or 24 single-ended inputs per ADC. It also includes three 12-bit buffered DAC outputs, eight windowed comparators with DAC references, and hardware post-processing - enabling synchronized current/voltage sensing, fast overcurrent protection, and closed-loop analog feedback without CPU intervention in F28384DZWTQR-based designs.

Is the F28384DZWTQR qualified for automotive applications?

The F28384DZWTQR itself is not automotive-qualified; however, its pin-compatible variant F28384DZWTQR-Q1 is AEC-Q100 Grade 1 qualified (–40°C to 125°C ambient) and certified to ISO 26262 ASIL B. While F28384DZWTQR shares identical silicon functionality and safety architecture, only the -Q1 suffix denotes formal automotive qualification - essential for use in EV on-board chargers, battery management gateways, or ADAS power supplies where F28384DZWTQR-Q1 is required for compliance.

What package type is used for the F28384DZWTQR?

The F28384DZWTQR uses a 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16 mm × 16 mm with 0.5-mm pitch. This thermally enhanced, lead-free, green-compliant package provides superior power dissipation and signal integrity for high-density industrial PCBs - especially critical in motor drive and inverter applications where F28384DZWTQR operates continuously at elevated junction temperatures.
